Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, in which the walls of the organ are thickened and its capacity or volume is diminished. Sarcomeres are added in parallel, as for example occurs in hypertrophic cardiomyopathy. In the heart, concentric hypertrophy is related to increased pressure overload of the heart, often due to hypertension and/or aortic stenosis. The consequence is a decrease in ventricular compliance and diastolic dysfunction, followed eventually by ventricular failure and systolic dysfunction.
